Abstract

PURPOSE:To hold a line without using a transmission control precedure of non- standard by transmitting continuously a flag field at a required step in the transmission control procedure so as to hold the line then transmitting a required control signal. CONSTITUTION:When a line hold request is detected, a control signal transmission means 73 controls a flag field transmission means 72 so that a short flag field is transmitted before the control signal until a DIS signal arrives and a long flag field is transmitted just after the DIS signal is incoming and moreover a short flag field is transmitted before the control signal after the control signal in succession to the said long flag field, and transmits the required control signal except the flag field. If no line hold request is detected, the means 73 controls the flag field transmission means 72 so that short flag fields are all transmitted before the control signal.

After a certain white transmission is completed, the next time the transmission is overturned (it takes some time to set it to Zokuno 17x, so it is necessary to maintain the line during this time (maintaining the line connection status 1.'I). , - used control signals according to the transmission control procedure 311 of the J1 standard.

[Problems with Seibaku Techniques] However, when using a control method based on a non-42-wall transmission control procedure, this control method can be used for a 1-hour fixed one-horn kushimiri device. However, for other devices other than the above-mentioned specific Tsuno-Kushimiri equipment, it is treated as a meaningless control function, and what is line maintenance? It has a completely different meaning and is treated as a 4 right control 1 iris code. Therefore (

The purpose is to provide a transmission control system for non-wireless devices that allows line maintenance without the use of non-standard transmission control procedures.

Even if the line maintenance ends r after that, if the length of the flag field is 2 or more C, CC11'-1 recommendation,
Since it does not appear as T, 30, the EOP signal is sent after the flag field is removed, and the communication ends normally. In this case, in the noro chart in Figure 2,
The process proceeds from step 110 to step f115.

FIG. 6 shows that the transmission of the flag field has started, but since no transmission request or line hold termination request is received during the transmission of the flag field for a predetermined time, the flag field is followed by (excluding the flag field < D CN signal). k to send it.

In the 7' axis device on the receiving side, the DCN signal is received after transmitting the [)IS, so if this procedure is performed, it is possible to detect an abnormality in the 77 axis device on the transmitting side. It is. In this case, by including the above-mentioned abnormality information in the communication management information of the receiving side facsimile machine, it is useful for maintenance of the sending (Z side facsimile machine).

Based on all the data held by the Kushimiri device, the flag field sending means 72 sends out 4J' following the flag field.
1. Control signal sending means for sending control signals excluding the flag field.

For example, if a line hold request is detected, the control signal sending means 73 sends out a short (usually 1 or 2) flag field before the control signal until the arrival of the DIS signal. I) Immediately after the arrival of the IS signal: In order to ensure that a long flag field is sent out, further control signals after the control signal following this flag field are preceded by unknown information. The control unit 72 controls the non-gone twird sending means 72 to which the goono-ird is sent, and sends out the necessary control signals except for the no-gno-ird.

In addition, if a line holding request is detected (-), all short flag fields are sent out before control number 15. - Determine what control signal C1 should be sent following the long flag field sent by the flag field exiting means 12 based on the line holding line data, transmission request data, etc. given to the control signal sending means 13. do.

As described above, in this embodiment, when the line should be held, the flag field is sent out for a longer time than usual after the [) IS signal sent from the receiving facsimile machine. There are some methods that provide suitable transmission control procedures to secure time.

[Effect of the Invention 1] As explained below, according to the present invention, by continuously transmitting the flag field,
It is possible to maintain the concave 1ω line between C1 and the axial line device by using a special control signal for line holding. It's very convenient.
